Anyone know what deficiency this is?

[budrow]

I have 4 clones going right now. They are a couple months old and are about to be flipped to flower soon but I just started noticing the leaves on 2 of them starting to look like this. Any ideas? I was thinking possible mag deficiency but wasn't too sure. Thanks!

Looks like an early stage potassium def, what ratios of feed are you feeding?
What’s the ph ppm?
Has the growth slowed down?

I have been using 10ml of grow big, 10ml of silica per gallon every other watering. I have now been adding in 5ml of cal mag to see if it helps. I've been PHing to 6.0. It seems like the growth has slowed down some

I’ve never used fox farm personally,
Grow big is a 6-4-4 npk
I use adv nutes 3 part witch totals something like 4-3-8 on just the base nutes no additives, if no results from the cal mag, maybe try something with a little more K in it, I’ve added this chart I’m sure you’ve got one but just have a look to see if u need to add some different additive or base, the def seems to be more on the lower leafs which tells me it’s a mobile deficiency
Md looking at this chart compared to your photos, the yellowing of the inner part of the leafs is why I’m leaning on potassium or (k) I hope this helps or atleast makes sence

Honestly I just googled big bud to try and help I’m not familiar with fox farm at all, I run advanced nutes in hydro

They seem to be doing a little better after the cal mag, I also just flipped to flower so I'll be adding the phosphorus and potassium soon to see how they do with that too.

hey man, not sure if you're aware, but when using silica; it must be mixed in water

1st, then calmag, then base, then the rest; if not it can cause problems:

"Silica has a unique chemistry and can easily bind with calcium or phosphorus if added out of sequence.
Following the correct order prevents nutrient lockout, ensures all elements remain bio-available, and avoids cloudiness or precipitation in your nutrient solution."

hope it helps -

-peace-

ps * i use general hydroponics in hydro - i follow that order,

bc that's how i was taught and it works for me. here is the

trunk on my baby.she is 38 days from seed

I haven't been mixing it first. I see it on the bottle now lol thanks for the info! I will start mixing it the right way and see how it goes.
